I REALLY NEED I JUST HAVE TO DO TWO MORE STUFF TO FINISH SCIENCE BUT I STILL NEED TO ALGEBRA I HAVE UNTIL FRIDAY TO FINISH SCIEN
CE AND ALGEBRA IF I DONT FINIH ALGEBRA AND SCIENCE I WILL NEED TO PAY 100 IN TOLTAL BUT I FINISH SCIENCE TODAY JUST 50 PLEASE HELP I BEG YOU. Materials needed:
Large glass measuring cup (2 cups or bigger)
Blue food coloring
Vegetable oil (any type of cooking oil)
Liquid dish detergent
Procedure:
(4 points for each question)
Fill the cup two-thirds of the way with water. Add a few drops of blue food coloring to make your “ocean.”
Pour 1/3 cup of oil into the ocean.
Answer the following questions:
What happens to the oil when you first pour it in?
Why does this happen?
What kinds of animals would be most affected by an oil spill at the beginning? Why?
Use a spoon to stir the oil for 30 seconds.
Answer the following questions:
What natural action stirs the real ocean?
What happened to the oil?
Even if you can’t see it, is all the oil still in your ocean?
Which animals in the ocean become affected after wave and current action causes some of the oil to settle to the bottom, or be absorbed into the water?
Add a splash of dish detergent to the mixture and stir.
Answer the following questions:
What happened to the oil? Is it all still in the ocean?
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done?
What might be a negative effect of dumping the soap?
Submit this assignment to your teacher when you are finished.
We know that oil floats on water and do not mix <span> What happens to the oil when you first pour it in? It flows into the water, but then seperates.
Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same
What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans
Use a spoon to stir the oil for 30 seconds.
Answer the following questions: What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation What happened to the oil? went back to the top Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and current
action causes some of the oil to settle to the bottom, or be absorbed
into the water? bottom-feeders Add a splash of dish detergent to the mixture and stir.
Answer the following questions: What happened to the oil? it mixed with the water Is it all still in the ocean? yes Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil What might be a negative effect of dumping the soap?</span> soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants
Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged.
To show the different levels of classification and divide among species, and different organisms on planet Earth. It also creates a universal "language" for scientists around the world when referring to organisms (cougar & puma are the same animals; different name) Example: The American Alligator and the Chinese Alligator (look it up!) are in the same family and genus, but are not the same species.
